The US Defense Department said Wednesday it was slashing participation in what was planned as the largest joint US-Europe war games in 25 years due to the threat of coronavirus transmission.

"After careful review of the ongoing Defender-Europe 20 exercise activities and in light of the current Coronavirus outbreak, we will modify the exercise by reducing the number of US participants," the US European Command said in a statement.

While the highest priority elements of the exercises in May and June will go ahead, "the health protection of our force, and that of our Allies and partners, is a top concern," the statement said.

About 37,000 soldiers from 18 NATO countries were to participate in the US-run manoeuvres planned for Germany, Poland and the Baltic States.

The Pentagon was to send more than 20,000 soldiers to Europe for the exercises.

They did not say by how much the number would be reduced.

It was the latest military exercise to be curtailed in the wake of the outbreak of the COVID-19 virus, which has spread rapidly from China to much of the rest of the world.

On March 5, the US and Israel cut short their two-week Juniper Cobra 20 war games over the coronavirus outbreak.

South Korean and US forces also postponed indefinitely their forthcoming exercises after Seoul declared a "severe" alert at the end of February.

Norway cancels exercises with NATO over coronavirus
Oslo (AFP) March 11, 2020 –

Norway's armed forces cancelled an exercise on Wednesday that was meant to gather 15,000 NATO and allied soldiers from March 12-18 because of concerns over the new coronavirus.

"The coronavirus is out of control," the head of the army's operations centre, Rune Jakobsen, told reporters.

"We would rather preserve our army's combat capabilities so we can support society in the turbulent period to come."

The exercise had initially been expected to gather troops from a dozen NATO or partner countries, including the United States, France, Germany, Britain, Belgium and Sweden.

Organised by Norway in the far north, it was aimed at testing multinational capabilities in a high-intensity combat scenario in demanding winter conditions.

The Norwegian army wanted to "avoid being a burden on the civilian healthcare system", which had been expected to provide some personnel for the exercise, Jakobsen said.

Last week, the Norwegian army closed a military base in northern Norway after a soldier tested positive for the new coronavirus.

That is the only case detected in the Norwegian armed forces to date, but 240 soldiers are still in quarantine as a result, Jakobsen said.

On Saturday, Finland announced it would not be sending the 400 troops initially due to take part, because of the epidemic.
